William Bates of Arkansas

I am looking for information on William Bates (my g-great granddad) born abt. 1830 to 1840 married Rachel maiden name unknown, but possibly Biles.I don't know if William was born in Arkansas, but I believe he moved there.My Great Grandfather was his son William A. (could be for Allison or Alton) Bates born about 1860 or 70 married Dora Ann Oliver.I'm not sure if William A. was born in Arkansas, but that is where he lived and where my grandmother was born Winifred Bates b. 12/3/1898 had a sister Malda Bates.My g-grandfather was supposedly a judge or lawyer and very well off and influential.We still have mineral rights to some property he left in his estate in Scotts County, AR.
